LED flashing every 3 seconds
Faulty battery
The battery has a shorted element or has completely exhausted its capacity.
The device isolates the faulty battery and flags it with long, slow blinks on the matching LED, on the BDS200 unit and also on the MC-180 control panel. To reset it, reduce the connected load and switch the BDS200 back on via the 3-position switch.

LED flashing every 1 second
Overcurrent protection triggered
One of the two channels drew more than 120A
The overcurrent protection trips by itself: the relay contact opens and cuts that battery off. Turn the device off and back on to reset it manually.
DIY Safe
LED flashing every 2 seconds
Battery protection function activated
The battery voltage dropped below 9.5V.
The battery protection function disconnects every user once the voltage falls below 9.5V, to prevent irreversible damage - and if it keeps falling below 8.5V, the device shuts itself off entirely. To bring it back, reduce the connected load and switch the BDS200 back on via the 3-position switch.
